the top of the stove, and extending downward to a Ipoint opposite or adjacent to the junction .of the in- 01- boiler, and eduets the smoke, vapor, and gases into VJthe open air through the chimney-pipe, into which it discharges.

The water-tank may be tted to receive one or more boilers, audits contents may be drawn out through a faucet, or iny any other suitable manner.

In the rear end of the upper compartment of the oven is adampcr, Q, through whose agency the odors, steam, gas, and cxhalations, generated in the oven, are expelled or discharged into the vertical outlet O, and carried through thc chimney-pipe into the open air.

If desirable, the oven may be so formed, arranged, andconstructed as to project forward beneath the firebox, on aline with thel front 'of the ash-pit, and one o1' more vertical induction-lines, or their equivalents, may extend from the bottom of the hot-air chamber to one or both of the conduits K K, and discharge therein the heated `air thus derived and conducted from the hot-air chamber.

The induction-flue or-,ilues would, under such arrangement, biscct the lower compartment of the oven, and thereby create an additional compartment, in which the operation of cooking could be performed.

Slis the inner side of the oven-door, on the front of which, at or near the-center, is cast or .alixed a lug, l, on whose face is a vertical groove, U. v

On the jamb or outside stove-plate V projects a lug, W, having a sloping or angular face.

'lhe oven-door, upon closing, is lslightly raised, by a knob ou the outside, and the lug T, in part, passes over the lug N in an 'oblique direction, and the door is fastened by the interlocking of the lug W in the groove U. The door, to be opened, is slightly raised, as in closing, by which movement the two lugs become disengaged and detached, whereby the door.

is unfastened.

By this inode of locking the oven-door, its outer edges are closely and firmly compressed against the jaub or outside stove-plate, and thc oven is, in consequence, made air-tight. This arrangement, moreover, supercedes the use of right and left-hand oven doers, commonly used on cooking-stoves; by our method, on the contrary, the oven-doors can be used indiscriminately on either side of the oven, thereby avoiding the delay, inconvenience, and annoyance to which persons using cooking-stoves are Afrequently subjected upon the injury or fracture of an oven-door, which requires the substitution of a new one.

Y Cooking-stoves, constructed onvthe plan of our in vention, may he fabricated of any approveddesign, size, shape, materials, ornamentation, and nish, and may be adapted to burn hard or soft coal, wood, coke, peat, or other suitable fuel.

Te expressly disclaim any originality or right to the exclusive use of a griddle-hole in the bottom of an oven, and likewise the application of a waterboiler, water-back, or its equivalent, to a cookingstove, as the same have long been known and used.

'We claim as our iuveptionof the magazine or tire-box B, the partition F, the intermediate air-space between the wall B and thepartition F, the damper D, and the ash-pit E, or their several equivalents, arranged, constructed, andvoperating in the manner and for the purposes substantially asv described.

2. vThe combination of the partition F, the inletliuc H, the griddle-hole or aperture I, the damper Q, the conduits K K, the horizon-tal Hue L, the flue-strip M, the reverse eduction-llue N, the outlet O, and the orice or v ent P, and their several equivalents, arranged, constructed, and operatingin the manner and for the purposes substantially as described.

3. The combination of the magazine or irebox A, the hot-air chamber C, the oven G, bisecte'd by a. transverse flue that conducts, diiuscs, and circulates heated air from the hot-air chamber throughout. each compartment of the oven, and the water-tank R, fabricated, arranged, and operating in the manner and for the purpose substantially as described.
